The character icons and portraits can be changed during the game. It's under the encamp->alter menu I think. The designer can choose a pool of images to make available to you during character creation and alter. You can add your own by copying your files to the design folder and renaming them properly. The icons are named icon1.pcx - icon50.pcx, the small pics (portraits) are spic1.pcx - spic50.pcx. The game will automatically load up files with those names when altering your character. The PCX extension is not important, any supported image format can be used.
You can also give a character a multi-icon image. Using the Logic Block event you can select which icon will used. Each icon is composed of two images, and each pair has an index (starts with 0 for first icon pair). Using Logic Block you set the index to another value and the game will offset into the icon image to retrieve that icon pair. Not sure if this is documented anywhere.
There is currently a limit of 100 pc/npc/monsters in combat.
